We began this series with a man who spent 1,000 days alone at a Shinto shrine in 1447. We end with men who carried the sword tradition into the streets of Kyoto on a summer night in 1864 and changed Japan's history by doing so.
This is School #10 of 10: Tennen Rishin-ryu - the sword school of the Shinsengumi.

Tennen Rishin-ryu was founded around 1789 by Kondo Kuranosuke Nagahiro, who had trained in Kashima Shinto-ryu (School #2 in this series) before building something new. He recognized that Japanese swordsmanship was at a turning point - the rigid classical form practice of the old schools was giving way to free sparring with bamboo swords and armor. He built his school to meet that moment: adaptable, practical, focused on full victory without losing composure in front of an enemy.
The school's name encodes its philosophy: tennen (natural, spontaneous), rishin (right principle, true heart). The ideal is a swordsman so deeply trained that technique flows without deliberation - responding naturally to any threat, without hesitation or rigidity.

The school's center of gravity was the Shieikan dojo in the Tama district near Edo. Because many of its students came from farming communities rather than samurai families, it was mockingly called the "Imo Dojo" - the Potato Dojo. The nickname didn't last. The swordsmen it produced did.
A young man named Miyagawa Katsugoro arrived at the Shieikan around age 15. He was eventually adopted by the school's third headmaster and took the family name - becoming Kondo Isami, 4th headmaster of Tennen Rishin-ryu and commander of the Shinsengumi. Among his training partners were Hijikata Toshizo, Okita Soji - who entered the school at 9 and had mastered its techniques by 14 - and Inoue Genzaburo.

The most famous night in the school's history was June 5, 1864: the Ikedaya Incident. Kondo led ten men - wearing steel helmet and chainmail beneath his kimono - into a Kyoto inn where twenty to thirty loyalist ronin had gathered to plot arson and attacks on sh**unate forces. Eight were killed. Twenty-three arrested. The Shinsengumi lost one man immediately, two more to later wounds. The incident made them famous throughout Japan - and in 2020, researchers discovered the exact helmet and chainmail Kondo wore that night, hidden at a temple in Toyama Prefecture for 150 years, bearing a snake-eye emblem.
The school's legend is inseparable from its tragedy. Okita Soji - the prodigy - collapsed during or after the Ikedaya fight, coughing blood. He died of tuberculosis aged 24 to 26, never seeing the end of the war. Hijikata Toshizo fought on after the sh**unate's fall, dying in the very last battle of the Boshin War on Hokkaido in 1869. Kondo Isami was captured and executed in April 1868.

They fought on the wrong side of history. The sh**unate they defended was dismantled. And yet Kondo, Hijikata, and Okita are among the most enduring figures in Japanese cultural memory - the subject of countless novels, films, anime, and manga across four generations. The school they practiced is still taught in the Tama district of Tokyo today, under two surviving lineages.
